Hi Rosie -
I'm glad you've found us! This is a VERY supportive, active community.
We have lots of forums you can check out...from groups by age range and eating plan to groups by amount to lose...you might check out the "300+ Club" or the "100 Lb. Club" to start. The first is for those with starting weights close to or above 300 lbs, the second is for those working toward losing 100 lbs or more.
Wherever you settle, jump on in. Can't wait to hear more from you soon!
